V. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Generally referring to FIGS. 1 through 31, particular embodiments of an earpiece (1) can include one or more of: an intra-auricular support (2), a projection element (3), a flexible body (4), and a moldable earpiece material (5). The intra-auricular support (2) can have an outer surface (6) opposite an inner surface (7), where each surface extends to an intra-auricular support peripheral edge (8). The intra-auricular support (2) extending to the intra-auricular support peripheral edge (8) can be configured to be positioned within an auricle (9) of the ear (10). As to particular embodiments, the intra-auricular support (2) can be positioned within the area of the auricle (9) of the ear (10) anatomically defined by the antihelix (11), tragus (12), antitragus (13), and concha (14), also referred to herein as the concha bowl (15), and concurrently defining an inner surface (7) of the intra-auricular support (2) of sufficient area which precludes ingress of the external ear canal opening (16)(as shown in the example of FIG. 7). For purposes of this invention the term “external ear canal (17)” means the portion of the ear canal (or auditory canal) communicating between the auricle (9) of the ear (10) and the tympanic membrane (19). For purposes of this invention, the term, “auricle (9)” means the area of the ear (10) outside of the external ear canal (17) including the concha bowl (15) and extending to the peripheral edge (20) of the ear (10)(also referred to as the “ear pinna”).

Now referring primarily to FIGS. 3 and 7, as to particular embodiments, the intra-auricular support (2) can be configured to be positioned in the concha bowl (15) concurrent with the flexible body (4) engaged with the external ear canal (17). While the intra-auricular support peripheral edge (8) of the embodiment shown in FIGS. 3 and 7 generally defines a quadrilateral having a pair of linear opposed sides (21) interconnected by a pair of arcuate sides (22), this example of the configuration of the intra-auricular support (2) is not intended to preclude other configurations of the intra-auricular support (2) in which the intra-auricular support peripheral edge (8) can generally define a circle, an ellipse, triangle, or other configuration disposable in the auricle (9) of the ear (10) and, more particularly, disposed within the concha bowl (15).

Now referring primarily to FIGS. 7 and 10, the intra-auricular support (2) can be configured to be disposed in the concha bowl (15) and retained in the concha bowl (15) by contact of the antihelix (11), antitragus (13), or tragus (12) with the corresponding portions of the intra-auricular support (2). As shown by the example of FIG. 7, a top portion (23) of the intra-auricular support peripheral edge (8) can be disposed behind the antihelix (11), and the lower portion (24) of the intra-auricular support peripheral edge (8) can be disposed behind the antitragus (13) and tragus (12).

Embodiments of the intra-auricular support (2) can fabricated, formed or molded from a wide variety of rigid or elastic thermoplastics including, but not necessarily limited to, acrylic, nylon, acrylonitrile butadiene styrene, polylactic acid, polybenzimidzole, polycarbonate, polyether sulfone, polyethylene, urethane, silicone, or combinations thereof.

Now referring primarily to FIGS. 4 and 5, particular embodiments of the earpiece (1) can further include a projection element (3) outwardly extending from a location on the inner surface (7) of the intra-auricular support (2) which aligns the projection element (3) within the external ear canal (17) concurrent with the intra-auricular support (2) being disposed within the auricle (9) or concha bowl (15) of the ear (10). As to particular embodiments, the projection element (3) can be disposed on, coupled to, or directly coupled to the inner surface (7) of the intra-auricular support (2) at a location where the projection element (3) extends into the external ear canal (17) concurrent with the intra-auricular support (2) being disposed within the concha bowl (15) locating the inner surface (7) adjacent to the external ear canal opening (16). As exemplified in FIGS. 4 and 5, the location from which the projection element (3) can extend, the bottom portion of inner surface (7) of the intra-auricular support (2), can be proximate the intra-auricular support peripheral edge (8). The projection element (3) can be configured as a solid or tubular elongate member having circular, oval, square, rectangular, or cross sectional configuration otherwise disposable in the external ear canal (17).

The projection element (3) can comprise the same material(s) or different material(s) as the intra-auricular support (2), and as to particular embodiments, the intra-auricular support (2) and the projection element (3) can, but need not necessarily, be fabricated, formed or molded in one piece.

Again, referring generally to FIGS. 1 through 5 and FIGS. 10 through 31, particular embodiments of the earpiece (1) can, but need not necessarily, include a flexible body (4) disposed about the projection element (3). The flexible body (4) can be disposed inside of the external ear canal (17) of an ear (10) concurrent with the intra-auricular support (2) engaged within the auricle (9) or the concha bowl (15) with the inner surface (7) adjacent the external ear canal opening (16). Embodiments of the flexible body (4) can, but need not necessarily, comprise any one or a combination of pliant materials or bladders which deformably compress upon engagement with the external ear canal (17) and return toward the original configuration upon disengagement with surfaces of the external ear canal (17), such as foam, foam rubber, or hydrogel. As to particular embodiments, the flexible body (4) can further include a continuously smooth external surface (25).

As to particular embodiments, the flexible body (4) can, but need not necessarily, be integrated with the projection element (3) as one piece or, as to other embodiments, removably coupled or connected to the projection element (3), as illustrated in the example of FIG. 4. In particular embodiments where the flexible body (4) removably couples to the projection element (3), the flexible body (4) can include a passage (26) disposed in the flexible body (4) and configured to accept the projection element (3). As illustrated in FIG. 5, the projection element (3) can be configured as a solid cylinder which can insertingly disposed in the flexible body passage (26) of the flexible body (4). As to particular embodiments, the flexible body (4) can further include a flexible body conduit (27) having a flexible body conduit internal surface (28) which defines the flexible body passage (26) and an external surface (29) which engages the flexible body (4). The flexible body conduit (27) can further include an annular flange (30) extending radially outward from the passage first end (31) toward the external surface (29) of the flexible body (4). As to particular embodiments, the flexible body conduit (27) and the annular flange (30) can comprise one piece. In other particular embodiments, as illustrated in FIGS. 1 and 3, the flexible body conduit (27) can, but need not necessarily, comprise two components where the first component (32) comprises the flexible body conduit (27) disposed within the passage (26) of the flexible body (4), and the second component (33) comprises the annular flange (30) coupled to the flexible body first end (34) and radially extending outward from the first component (32) disposed in the passage (26) toward the external surface (29) of the flexible body (4).

Now referring primarily to FIGS. 6A and 6B, and 11 through 13, 17, 18, 22, 23, 27 and 28, particular embodiments of the earpiece (1) can, but need not necessarily, further include a moldable earpiece material (5). The moldable earpiece material (5) can be molded about the intra-auricular support (2) to conform to the auricle (9) or the concha bowl (15) of the ear (10). The moldable earpiece material (5) can, but need not necessarily be, a single compound (35) (shown as compound “A” in FIG. 6A).

As to other embodiments, the moldable earpiece material (5) can, but need not necessarily, comprise a two-part moldable earpiece material (37) including or consisting of a moldable agent (38) (shown as compound “A” in FIG. 6B) combinable with a curing agent (39) (shown as compound “B” in FIG. 6B) which can be mixed together prior to molding to form a single mixed compound (40) (shown as compound “AB” in FIG. 6B) capable of being moldable about, coupled to, or adhering to the intra-auricular support (2) by forcibly urging the single mixed compound (40) onto or about the intra-auricular support (2) (as shown in the example of FIGS. 11 and 12, 17 and 18, 22 and 23, and 27 and 28). Concurrently, the moldable earpiece material (5), whether a one-part moldable earpiece material (36) or a two-part moldable earpiece material (37) to provide a single mixed compound (40), can be molded to the contour of the auricle (9) or the concha bowl (15) of the ear (10) (as shown in the example of FIGS. 12 and 13, 17 and 18, and 22 and 23). After molding about the intra-auricular support (2), the single compound (35) or single mixed compound (40) can then cure over a period of time at ambient temperature (or at a temperature greater or lesser than ambient temperature) to provide a fixed configuration of the moldable earpiece material (5)(as shown in the examples of FIGS. 13, 18, and 23).

In embodiments including a moldable earpiece material (5) comprising or consisting of a single compound (35), the single compound (35) can include or consist of one or more of: ethyl vinyl acetate, polycaprolactone, silicone, or like thermoplastic materials. Single compound (35) moldable earpiece materials (5) transition from a moldable condition to the fixed condition by exposure to external factors such as moisture, temperature, or ultraviolet light.

As to particular embodiments, the adhesion elements (42) can be configured as patterned surface elements (44) disposed on or in the outer surface (6) or inner surface (7) of the intra-articular support (2). The patterned surface elements (44) can provide an irregular or uniform pattern, texture, or roughness sufficient to fix or reduce travel of the moldable earpiece material (5) on or about the intra-auricular support (2). As to certain embodiments, the patterned surface elements (44) can provide recesses disposed in the intra-auricular support (2), which can function to sequester the moldable earpiece material (5) (as shown in FIG. 8), or provide protuberances that extend outward of the intra-auricular support (2) to penetrate the moldable earpiece material (5), or combinations thereof. The patterned surface elements (44) can be one piece with the intra-auricular support (2) or can be applied to the intra-auricular support (2) as a layer or individual elements.

Now referring primarily to FIGS. 9A and 9B, as to particular embodiments of the intra-auricular support (2), the adhesion elements (42) can comprise a tackifier (43) (shown in FIGS. 9A and 9B as compound “C”) incorporated into the moldable earpiece material (5) or applied to the inner surface (7) or the outer surface (6) of the intra-auricular support (2) to increase the tack, or stickiness, of the moldable earpiece material (5) or intra-auricular support (2). As illustrative examples, the tackifier (43) can include or consist of one or more of rosin resins, hydrocarbon resins, terpene resins, or other like materials.

Now referring generally to FIGS. 14 through 31, particular embodiments of the earpiece (1) can be provided separate from, but capable of use with, one or more of a wide variety of in-ear devices (45), for example: earphones, earplugs, earbuds, sealing balloons, ear tips, ear tubes, ear speakers, and in-ear hearing aids, or the like. As to particular embodiments, the in-ear devices (45) can be a part of an apparatus worn or which resides outside of the ear (10), for example: headsets, head phones, telephones, BLUETOOTH® headphones, wireless headphones, hearing aids, medical apparatus, or the like.

Particular embodiments of the earpiece (1) capable of use with an in-ear device (45) can include an intra-auricular support conduit (46) communicating between the outer surface (6) of the intra-auricular support (2) and the inner surface (7) of the intra-auricular support (2). The intra-auricular support conduit (46) can have an intra-auricular support conduit internal surface (47) configured to retain or releasably retain the in-ear device (45) in the earpiece (1) and which defines an intra-auricular support passage (48).

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of an earpiece which can be utilized for the production of an earpiece by the process above described.

As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.

It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of “a moldable earpiece material (5)” should be understood to encompass disclosure of the act of “molding an earpiece material”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “molding an earpiece material”, such a disclosure should be understood to encompass disclosure of “a moldable earpiece material (5)” and even a “means for molding an earpiece material.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.

In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.

Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity; for example, “an earpiece” refers to one or more of the earpieces. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.

All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result.

Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.

Thus, the applicant(s) should be understood to claim at least: i) each of the earpieces herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
